Equipment, Instrument and Pipes in the Explorer

For each drawing, items are grouped under one of three headings: Equipment, Instrument Loop and Pipes.

• The Equipment heading groups together all equipment items. Equipment items can in turn be collections of items, and this is represented in the Engineering Explorer that displays the hierarchy of items within an equipment collection. The nozzles, trim, trim branches, sub-equipment associated with a top-level equipment item are displayed.

  

  Note: Items can also be displayed under Engineering Group headings. Refer to Engineering Groups in the Explorer.

• Under the Instrument Loops heading is a list of the instrument loops on the drawing. Instruments are listed under the appropriate loop node. Instruments that are not in a loop are grouped under a node called "UNNAMED". Instruments can be assigned to loops by dragging and dropping between loop nodes.

  

• The Pipes heading groups together all the pipes on the drawing, plus the hierarchy of all the branches of each pipe. Inline piping components are not currently represented.

  Note: Pipes will not be displayed in the Engineering Explorer until they have been labelled.

• The part of the pipe that has been labelled as the "main" pipe label is displayed at the top of the hierarchy of a pipe and its branches. If no main pipe label has been set, the pipe start node properties assume this position by default.

  

• Under the Pipes heading, beneath the list if pipes, pipe groups may be specified for reporting purposes, refer to Create Pipe Groups. Pipes may be assigned to these groups by dragging them from the list of pipes dropping them into the appropriate group.

  

• Valves associated with a pipe can be displayed, refer to Valves Configuration Category.

  

• Where the label or tag of an item is displayed in red, this indicates that the item is invalid in some way. This occurs when the label of the item has not been sufficiently completed, or in the case of nozzles, not labelled at all.

• The labels of typical items may also be displayed in distinct colours, as specified in the project settings. For example, typical instrument labels may be set to be green in colour. This colour is used for the label both on the drawing, and in the Explorer.

Context Sensitive Menus for Items

When selected, items in the Engineering Explorer have shortcut (right-button) menus.

• The Refresh option is used to regenerate the Explorer hierarchy.

• The Sort option that is used to sort all the items displayed in the Engineering Explorer according to their labels.

• When the Find option is selected, the selected item will be zoomed to on the drawing. If the drawing display does not currently show the item (for example, if the item is not within the current drawing view window, the drawing view window will change accordingly.

• The Move, Copy and Delete options can be used to perform these actions on individual items, or on collections of items. For example, these options can be used to move, copy or delete a single branch, or an entire pipe collection including of the branches of the pipe.

• The Properties option opens the Properties dialog for the selected item, which can be used to enter the labels and other details of the item. Refer to Properties Dialogs.

• The Instrument Loop node menu includes a New Loop option, used to create new instrument loops. Refer to Create Instrument Loops.

• The Pipes node menu includes a New Group option, used to create new pipe groups. Refer to Create Pipe Groups.
